one.CCZ-20 Mining Dust SamplerIntroduction

CCZ - 20The type of mining dust sampler is based on《MT162-1995Technical Conditions for Dust Samplers《JJG(coal)03-96Verification Regulations for Mining Dust Samplers《GB16225-1996Hygiene standard for respiratory silica dust in workshop air《GB16238-1996Hygienic standard for respiratory cement dust in workshop air《GB16248-1996Hygienic Standards for Respiratory Coal Dust in Workplace Air《GB5748-85Methods for determination of dust in workplace air "and《MT79-84The selection and arrangement of measuring points in the working area above and below the well, as the method for measuring dust concentration and dispersion, is a conventional instrument designed and manufactured for measuring the concentration of airborne dust in the ambient air. Suitable for dust monitoring in industrial and mining enterprises, labor safety, labor hygiene, and environmental protection departments.
This dust sampler consists of a high-performance suction pump, automatic time control circuit, flow regulation circuit, automatic feedback constant current circuit, undervoltage protection alarm circuit, safety power supply, etc. It is also equipped with various dust pre collectors. The total dust pre collector is used to measure the total dust concentration; Another type of impact pre collector used to determine the concentration of respiratory dust, which can separate respiratory dust and non respiratory dust that are harmful to the human body. It can collect both respiratory and non respiratory dust samples at once, and its separation efficiency reaches internationally recognized standards“BMRC”Curve standard is a reliable and practical dust pre separation device. This instrument adoptsibI(150)℃)The intrinsically safe explosion-proof structure is particularly suitable for use in coal mines and other workplaces containing explosive gases.
The chassis of this machine adopts high strengthABSEngineering plastics have undergone special treatments for moisture, dust, and static electricity prevention. The instrument has the advantages of no pulsating airflow, high negative pressure and load capacity, automatic timed sampling, safety and reliability, durability, easy portability and on-site use. Its main technical indicators have reached or are close to the international advanced level.
